Add D3D12 Backend for MultiDrawIndirect Feature

This CL adds support for the D3D12 backend, which requires emulation of
base vertex and base instance parameters in the indirect arguments.
The indirect draw validation compute pass duplicates the parameters if it is used in the shaders.
MultiDraw capability is supported on all devices with D3D12.
New tests added for MultiDrawIndexedIndirect to test baseVertex and firstInstance.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
